Application filed April 14, 1920. Serial No. 373,815.

To all whom t may concern.'

Be it known that I, JAMES W. Unna, citizen of the United States, residing at Carson City, county of Montcalm, and State of Michigan, have invented new and useful Improvements in lire-Twisters, of which the following is a specification. Y

This invention relates to tools, particularly to wire twisting devices for applyingV wire to bales and the like, and has for its object the provision of a novel wire twisting device adapted for use in the chuck of an ordinary breast drill and which includes means for clamping the ends of a wire tight and which further includes means for cutting the wire after a twist has been made therein. n

An importantobject is the provision of a device of this character which isprovided with a removable member interposed in the end portion which will assist in the proper twisting of wires of different sizes, a plurality of these members being provided, all of which are interchangeable.

An additional object is the yprovision of a device of this character which will be simple and inexpensive in manufacture, easy and efficient in use, durable in service, and a general improvement in the art.

With the above and other objects and vantages in view, the invention consists in the details of construction to be hereinafter more fully described and claimed, and illustrated in the accompanying drawings in which- Figure 1 is an elevation of my device, showing it associated with a breast drill,

Fig. 2 is an enlarged side elevation of my device detached,

Fig. 3 is a longitudinal sectional view,

Fig. 4 is an elevation taken at right angles to Fig. 2,

Fig. 5 is an elevation of the opposite side,

Fig. 6 is a cross sectional view taken on the line 6 6 of Fig. 4, and

Fig. 7 is a detail View of one of the removable nostril members.

Referring more particularly to the drawings, the numeral 10 designates the bodyV tral hole 12.

Vare spaced ears 14 between which is pivoted,

as at 15, a cutting member including a bar 16 carrying at its end a pivote-cl blade 17 adapted to enter and fill the recess or notch 13. The edge of this blade is of course sharpened so as to haveV a cutting action. l also provide a spring 18 located between the ears 14 and normally urging the bar 16 in such a direction that the blade will be in non-cutting position. Also pivoted betweenthe ears 14 is a lever '19 having one end formed as a handle diverging` from'the body 10 and having its other endY engaging beneath the freeend of the bar 16. l/Vhen the operator1 grasps the device and squeezes the lever 12 toward the body the blade 17 will enter the notch or recess 13.

Formed in the body 10 at the side opposite the ears 14, isa recess 20 which communicates by a hole 21 with the central hole 12. Pivoted within this recess 20, as shown at 22, is a lever 23 having a cam head 24 acting as a clamp for engaging and holding wires inserted within the device and eX- tending along the recess 20.

Removably disposed within the hole 12 is a nostril member 25 which has a bore with a flaring entrance end 26. rlfhis nostril member is held in position by a suitable set-screw 28 passing through one side of the body. 1f preferred, the flaring end of this bore 26 may be provided with oppositely arranged shoulders 27.

The use of the device is as follows:

Assuming that a length of wire is passed about a bale, boX, or other article which it is desired to secure, the ends of this wire are passed through the bore of the nostril member 25 and are passed through lthe hole 21 and extended along the recess 20. rlhe operator then squeezes the cam lever 23 against the body whereupon the cam head 24 thereof will clampingly engage the wires within the recess 20. The operator then rotates the operating wheel or handle of the drill and this results in rotation of the entire device and this will of course cause a twisting together of the ends of the wire. made the operator presses upon the lever 19 which will force the cutting blade 17 into the notch or recess 13 and eect severing of the wire. The ends cut oilE will then drop out of the recess 20 when the lever 23 is moved outwardly.

After the twist is It will be observed that when different sizes or" wire are to be used that there would be a plurality ot the nostril members 25, all having bores ot' different diameters so that the different sizes of wires may be accommodated. ln the event that the nostril member used is provided with the shoulders 27, it will be seen that these shoulders will engage against the wires and assist in making a proper twist.

From the foregoing description and a study of the drawings it will be apparent that l have thus provided a simply constructed and easily operated wire twisting device which is provided with eilicient clamping means and which has anovelly arranged cutting mechanism in addition to the interchangeable guide or nostril members for accommodating different sizes oit wires. lt will be apparent that in actual practice it will be unnecessary to make very many twists and it will consequently be seen that probably a single rotation oit' the drill handle will be sufiicient. Owing to these facts it will be seen that the device may be used with considerable speed and that the wire twisting operation will involve but little eiiort and be a material time saver.

While l have shown and described the preferred embodiment of my invention, it is of course to be understood that I reserve the right to make such changes in the form, construction, and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, l claim:

l. A device of the character described comprising a body Jormed at one end for engagement within a drill chuck, said body being provided at its other end with a circular hole and a transverse recess intersectingthe hole, said body being formed in one side with a longitudinal recess communicating with said hole, a lever pivoted within said longitudinal recess and having a cam head cooperating with the bottom of the longitudinal recess whereby to serve as a clamp, a movable cutting blade extending into said transverse recess, and a lever pivoted at one side of the body and connected with said blade.

2. A device ot the character described comprising an elongated body provided in one end with a circular hole and formed with a lateral recess intersecting the hole, the body being further provided on one side with a longitudinal recess into which said hole leads, clamping means within said longitudinal recess, cutting mechanism extending into said transverse recess, the other end of the body being provided with a counterbore, a removable nostril member disposed within the counterbore and having a bor with a iiaring entrance end, and a set screw for holding said nostril member in position.

3. A device of the character described comprising an elongated body adapted for engagement within a drill chuck and provided at one end with a central hole, the body having a il-shaped transverse recess intersecting said hole and being also provided with a longitudinal recess into which said hole leads, wire clamping means within said longitudinal recess, and cutting mechanism including a bar pivoted on the side of said body opposite the longitudinal recess, a blade pivotally connected with said bar and operating within said transverse recess, a spring engaging said bar for normally holding the blade in inoperative position, and a pivoted lever having one end formed as a handle and its other end engaging the free end of said bar.

ln testimony whereof l hereto aHiX my signature.
